Big Agnes Seedhouse SL 3 -
The Big Agnes Seedhouse SL 3 is an extremely light 3 person end entry tent with 1 vestibule. The shockcorded, Hubbed, DAC aluminum frame is light, yet durable. It has 1 door that opens to a moderate storage vestibule. The all mesh body is great for ventilation and offers up star gazing opportunities on nice nights. On not so nice nights the full coverage SilNylon fly envelops the tent in a protective cocoon keeping you dry and happy. The Seedhouse SL tents are the tents that propelled Big Agnes into the big time. Check one out and see what the fuss is about.

The DAC hubbed pole design allows you to set up the tent in seconds and there is no guesing as to which poles go where. It's a tight 2 Person set up so if you require extra room you may want to look at a larger double door superlight tent. The Big Agnes Seedhouse SL2 is an ultra-light tent for those looking for the lightest solutions around.

SPECIFICATIONS of the Big Agnes Seedhouse SL 3 Person Tent.


There's no buts about it: the Big Agnes Seedhouse SL3 is the lightest free-standing three-person tent the Outdoor Gear Exchange has ever sold. Its packaged weight of 3 pounds 15 ounces breaks down to a mere 20 ounces each for three people, and it's an attractive two-person option as well for those who desire a bit of elbow room at a still-light 31 ounces per person. The low weight of the Seedhouse is a product of its architecture; a single ridge pole, single door, and single vestibule combined with an airy mesh tent body and gossamer rainfly keep it below four pounds. We wouldn't recommend pitching it at the foot of Cerro Torre in 90mph winds, but it's strong enough for the 3-season backpacking needs of most users.

Features: (Spring 2014)

Getting out of the elements is great, but longer wilderness trips can lose their luster if you have to lug around a heavy tent. The Big Agnes Seedhouse SL 2 tent provides tons of space and weather protection for you and a partner without weighing a metric ton—in fact, it has a decidedly un-tonlike trail weight of 2.5 pounds, which can be further reduced to two pounds even if you bring just the fly, pole, and footprint (sold separately). Super-light doesn't mean super-lame, either, seeing as the Seedhouse has a nylon ripstop fly and floor, coated with PU for extra waterproofing, and seams that are fully covered with solvent-free tape.

To pitch it in a jiff, just use the single DAC Featherlite hub-style pole, clips, and reflective guylines and webbing—the Seedhouse will be good to go in minutes, and you won't even trip over it in the dark. You'll be able to toss your gear in the vestibule, stash small items in the mesh pockets, and sleep the night away, no matter what the weather's up to. (Fall 2013)

Getting out of the elements is great, but long-distance trips can lose their luster if you have to lug around a heavy tent. The Big Agnes Seedhouse SL 2 tent provides plenty of sleeping room and solid weather protection for you and a partner without weighing you down. This lightweight tent is a smart choice for multi-day backpacking trips or treks when solid shelter is a must, and trimming weight is essential.

The waterproof fly and floor keep moisture out thanks to a polyurethane coating, and PVC-free seam taping helps prevents water from working in between the stitching. The front vestibule protects your gear or your canine camp buddy from the elements. The super-lightweight DAC Featherlite NSL poles utilize press-fit connectors and lightweight hubs to make setup lightening fast, and reflective guylines and corner webbing makes it easier to find—and not fall over—your tent after late-night bathroom trips.


The ultralight, freestanding Big Agnes Seedhouse SL3 tent is for weight conscious backpackers who like to count ounces and still have a little elbow room to read at night.

Positive Reviews:

Very psyched! Roomy with nice design.

Was originally looking for a two person and had ordered Copper Spur UL 2. Didn't like narrow top of Seedhouse SL2 design. Then saw Seedhouse SL3 with spreader cross pole. Bingo! Just a bit heavier than copper spur UL2 but with more durable materials/components and much more room. I've slept in it two rainy nights and stayed quite dry. Design is very nice. Like the single front door and interior height. Fly tensions nicely over tent and ventilation can be adjusted with guy lines.

This tent is HUGE

If you actually need a 3 person backpacking tent, this is perfect because it's huge inside. Bought this thinking it had a little more space than the Fly Creek ul 3, however is has ALOT more space than the F.C. Great quality, lightweight, and very easy to set up. More than enough space for two people and a dog. My boyfriend is 6'4" and his length fits perfectly.

Excited for all my future adventures with this tent!

I would buy this product again

I needed a tent that was small, light, easy to pack, and comfortable for two people. It had to have enough room inside for storage. This tent has it all. The only complaint is the set up is a little confusing if you don't use the tent for awhile. This is my second Big Agnes tent. My first wast the Seedhouse SL2. This is a great tent for two people.

Great tent

On my second outing this tent weathered a major thunderstorm and kept me and my gear dry.

Best backpacking tent I ever had.

Very light weight yet durable. Awesome 3 seasons backpacking tent.

Good but not great backpacking tent

I have used this tent at Philmont and at Isle Royale over the last two seasons and it stood up well. It can be put up by one person. I bought it instead of the SL2 because I am 6'2" 220 and my son isn't far behind. So I don't think the SL3 is a three person tent for people like me. I find the zipper on the vestibule to be annoyingly far away and when you're getting up in the middle of the night, it's not fun. It is important to make sure that all bottom stays are staked to ensure proper ventilation or there is a ton of condensation on the inside of the tent but if you do that you should be good.
